Study of the composition and properties of the beneficiation tailings of currently produced loparite ores

The increase in demand for rare earth metals and the depletion of natural resources inevitably causes need to search alternative unconventional sources metal raw materials. article presents results a study composition properties beneficiation tailings currently produced loparite ores. Sieve, mineralogical, chemical, radionuclide analyses were carried out. average content was determined. Using scanning electron microscopy, minerals-concentrators elements ore diagnosed. distribution valuable components thorium determined depending on particle size class. radium-thorium nature radioactivity established, values effective specific activity samples calculated. We concluded that it is necessary develop an integrated technology processing ore, due complex heterogeneous mineral chemical material.
